Wich facotr most directly contributed to the rise of terrorist groaups such as al qaeda

Al quaeda rose in protest of us, invading Kuwait. It was seen as us invading in other countries that we did not belong in, and so it radicalized a variety of people (not to mention the countless interventions we did) Also we funded the Muja Hadeen, which was the people who fought the Soviet Union, who eventually became Al Queda
